WebThe Double Helix is American scientist James Watson’s personal account of the discovery of the structure of DNA. He and Francis Crick succeed in determining the three-dimensional chemical structure of DNA in 1953, while they were working together at Cavendish Laboratory, at Cambridge University. WebThe double helix of DNA is, like its name implies, in the shape of a helix which is essentially a three dimensional spiral. The double comes from the fact that the helix is made of two long strands of DNA that are intertwined—sort of like a twisted ladder. Each strand of DNA (or side of the ladder) is a long, linear molecule made up of a ...
